Anatomia foliar de espécies de Bulbophyllum, seção Micranthae Barb. Rodr. (Orchidaceae) e sua correlação com a taxonomia

Orchidaceae é uma das maiores famílias de Angiospermas, com distribuição cosmopolita, sendo que Bulbophyllum é o maior gênero da família, com mais de 1200 espécies. A seção Micranthae apresenta 12 espécies distribuídas na América do Sul e com grande representatividade no Brasil. A interpretação das Orchidaceae de maneira geral, é dificultada pela grande diversidade de espécies, gerando problemas taxonômicos. Visando levantar caracteres diagnósticos para as espécies e estados de caráter compartilhados entre elas, foram realizados estudos anatômicos das folhas de 11 espécies de Bulbophyllum seção Micranthae e de outras três espécies de Bulbophyllum constituindo o grupo externo. As estruturas anatômicas: epiderme unisseriada com cera epicuticular espessa; estômatos tetracíticos com câmaras supraestomáticas; presença de hipoderme e de feixes vasculares colaterais caracterizam as espécies estudadas. A forma cilíndrica da folha de Bulbophyllum insectiferum Barb. Rodr. é caráter diagnóstico da espécie, assim como a ausência de idioblastos traqueoidais de paredes espessadas em Dendrobium kingianum Bidwill ex Lindl. A morfologia das folhas, forma da lâmina foliar em secção transversal, forma das células epidérmicas em vista frontal, tipo de mesofilo, tipos de cristais e número de feixes vasculares são caracteres que permitem agrupamentos entre as espécies analisadas. Esses caracteres serão utilizados numa futura análise cladística procurando auxiliar a filogenia do grupo

Algas verdes coloniais em riachos de Unidades de Conservação do Sul do Brasil: taxonomia e aspectos ecológicos

Species of colonial green algae from 10 Conservation Units from the Southern Brazil were surveyed. The samplings were carried out in 105 stream reaches, consisting of 10 m length transects. In addition to biological data, some environmental variables were measured: depth, current velocity, water temperature, turbidity, specific conductance, pH, dissolved oxygen and nutrients (total nitrogen and orthophosphate). Three species of colonial green algae [Bohlin Ecballocystis pulvinata var. pulvinata, Tetraspora gelatinosa (Vaucher) Desvaux and T. lubrica (Roth) C Agard] were recorded and these species were described and illustrated. Based on the environmental data, it was observed some patterns of ecological distribution, including the occurrence of E. pulvinata var. pulvinata in environments with higher water temperature and current velocity values, while Tetraspora species typically occurred in environments with lower total nitrogen, orthophosphate and specific conductance values.

Variação na cobertura vegetal nativa em São Paulo: um panorama do conhecimento atual

Studies in several countries have shown the occurrence of forest transition, when forest cover increase overcomes the loss by deforestation. In Brazil, although deforestation is still higher than afforestation, this relationship may be inverse in some regions. Recent assessments suggest the tendency of the state of São Paulo towards forest transition. Aiming to analyze forest transition evidence and facilitate the use of existing information, we review data on native vegetation cover variation in São Paulo from four data sources (Instituto Florestal, SOS MataAtlântica/INPE, IBGE and CATI/IEA). Our results indicate that discrepancies among these assessments may be accounted by differences in methodologies and objectives. We highlight their common grounds and discuss possibilities to harmonize their information.

Estrutura de um curso de taxonomia de campo: o modelo aplicado em Ubatuba, São Paulo

The field activities are essential for the education of a good taxonomist. The most common problems found in field activities are: a) large number of students, b) heterogeneous educational background and unlevelled knowledge of the participants, c) repetitions and tendency of collecting the more evidents life-forms. The causes and consequences of such problems are discussed herein. The proposed solution is a methodology, based on many years of experience in field courses for undergraduate and graduate courses. Topics about the ideal number of participants, area of coverage, period of activity, division of work and the necessary material and equipment are discussed. According to the number of species collected at the same place, this methodology may result in a list of local species with precise information about the life-forms, habitat, common names, frequency, uses, phenology and further information in this kind of work. The results of the aplication of this metodology in a field course held in the region of Ubatuba-SP are presented.

Notas sobre duas espécies de Thelypteris Schmidel (Thelypteridaceae - Pterophyta) do Brasil

During the taxonomic study of the Thelypteridaceae from southeastern Brazil was founded Thelypteris polypodioides (Raddi) C. F. Reed and Thelypteris villosa (Link) C. F. Reed, two rare and poorly known species. The taxonomic position of these species is uncertain. This study presents key, descriptions, illustrations, data on geographical distribution, and comments for both species, as well as comments on taxonomic affinity between the two species and Thelypteris subgenera.

Revisão taxonômica de Lonchocarpus s. str. (Leguminosae, Papilionoideae) do Brasil

A revision of the Brazilian species of Lonchocarpus s. str. is presented. This study is based on field observation and an analysis of approximately 1,200 herbarium collections. Nine species are recognized, L. cultratus, L. hedyosmus, L. latifolius, L. macrocarpus, L. nitidus, L. pluvialis, L. sericeus, L. spiciflorus, and L. violaceus, which grow in forests and are usually associated with river banks. Lonchocarpus sericeus and L. cultratus have a wide distribution throughout Brazil, whereas L. hedyosmus, L. macrocarpus, L. spiciflorus, and L. latifolius are restricted to the Amazonian domain. Lonchocarpus pluvialis occurs in the Central-West (Mato Grosso do Sul and Goiás) and Southeast (São Paulo) regions. Lonchocarpus violaceus is found in the states of Bahia and Espírito Santo, and is reported for the first time for Brazil. Identification keys, descriptions, and illustrations, in addition to information about habitat, geographic distribution and taxonomic and nomenclatural comments, are provided for the species. Four new synonyms and five lectotypifications are proposed.
